UNITED STATES PATENT 1 OFF C WALTER SOOTT,.OF PLAINFIELD, NEW JERSEY.

BED AND CYLINDER PBl NTlNG-MACHINE.

SPECIFICATION forming part of Letters Patent lvdssdsszdatea December 4,1894.

Application filed January 22,1891. semi lilo. s7s,717. (No model.)

To all whom it may concern: 1 Be it known that I, WALTER Scormga citizenof the United States, and a resident of f My invention relates primarilyto printing machines wherein the impression is taken between a cylinderand a flat bed on which the form is placed, and consists of combinationsof devices hereinafter set forth and pointed out in the claimsconcluding this specification.

My invention has for its objects, first, to print two complete copies,the sheets being in one length and printed on both sides, and to deliverthe sheets to a fly or a folding apparatus; second, to print on one sideofsheets, the sheets being of any length within the capacity of themachine, 0'. e.,'within the length of two complete copies, as spoken ofabove, and to deliver the sheets; third, to print on both sides ofsheets of various lengths and to deliver the sheets, and to attainvarious other results, as will hereinafter appear. I

attain these objects by the mechanism illus trated in theaccompanyingdrawingspin which-- Figure 1 isa side elevation of themachine, some of the smaller parts being omitted for the sake ofclearness. Fig. l showsa modification of certain parts. Fig. 2 is anenlarged elevation of part of the machine shown in Fig. 1, the partsomitted in Fig. 1 being shown herein, and one end of the machine beingomitted. Fig. 3 is an end elevation, partly in section, of the workingparts shown in Figs. 1 and 2. Fig. at is an end elevation of amodification of the motion changing devices. Figs. 5, 6, 7, and 8 arediagrammatic views showing the operation of the printing, reversing, anddelivery mechanisms at various stages. Fig. 9 is a side elevation ofanother modification of the devices for changing reciprocating motion oroscillatory-rotary mo tion into rotary motion. Fig. 10 is an endelevation, partly in section,'of the last modification. Fig. 11 is aview, partly insection on the line 7-7 of Fig. 9, ofthelastmodification.Fig. 12 is an endelevation of another modification of themotion-changing devices.

Fig. 13 is a view, partly in section on the line 13, of thelastmodification.

A suitable frame A supports the operating parts of the machine. The flatbed B on which the typeform' is secured has a reciprocating l motiongiven it by the rolling gear 0, which engages the racks D and E on thebed B and frame A respectively. The gear 0 is moved by the rod F andcrank-pin G. The pin G may be on a suitable crank on the shaft H, in thecenter of the machine, and the shaft be driven by the gear K at one endthereof, or the gear K may be placed in the center of the machine (inwhich case its size and location must be such that it will not interferewith the type bed B) and the wrist pin G may be on one side thereof. Thegear K may be driven by any suitable means, such as the ordinary belt36, pulley, 37, and gear 38. Shown in Fig. 1. Racks J, one on each sideof the type" bed B, engage with ring-gears L on the endsoftheoscillating impression cylinder M. Themechanism' thus far describedis of ordinary and well-known? construction.

I place inkingrollers N, N, adjacent the impression cylinder forpurposes hereinafter set forth. To carry out some of the objects of myinvention, it is necessary that the reciprocating motion of the typebed,or its rack or racks, J, rather, be changed into a practicallycontinuousrotarymotion'ormotions. Thernech anisms by means of which Ichange the motion of the rack J into the rotary motion referred to willnow be described.

A driver gear 0, in this instance having a diameter one half that of thecylinder M or gear L, is connected withthe latter in any suitable way soas to move rotarily therewith. I have shown it as being so connectedthrough the mediumof the impression cylinder and its shaft, since thisenables me to attainother objects of my invention. This driver-gear Ohas an oscillatory-rotary motion given itby the reciprocating rack J andgear L. To change the oscillatory-rotary motion of gears L and 0 intorotary motion, I employ two seg- These in a printing machine be gearedto the reversing and delivery cylinders. These segments may also beconnected by suitable cranks on their shafts (with which the segmentswould then be rigid) and connecting rods between the pairs of cranks orby link belts. In another instance, I place a segmental gear, as R, onthe side of a gear wheel Q in such a position that the segment may, atproper times, come into mesh with the driver gear 0, and I place asimilar segment gear S on a gear wheel P, which meshes with the gearwheel Q. The segments R and S approximate in length one half thecircumference of the gear wheels on which they are placed. I place thesesegments R and S relatively to the driver and to each other so that theyare separately and alternately in gear with the driver gear 0. The gearsP and Q mesh with each other but not with the driver gear 0. Thesesegments R. and S may be constructed so that the leading end of one orthe other will be in contact with the driver gear when the latterreverses its movement. This construction has some objectionable points,such as noise, due. I prefer, therefore, to have a small clearancebetween these segments and the driver gear in certain positions of theparts (in this instance, two such positions) and to use starter means tocause one or the other of the segments to gear with the driver. Thisclearance may be obtained by making the segments of such length thatthey will be out of mesh with the driver at or in certain positions, butI prefer to obtain this clearance by shortening the end teeth of thesegments, as shown at a, a, those teeth a, near the driver not beingmarked, so as to avoid confusion in the lines of the drawings.

To cause the engagement of either of the segments R and S with thedriver gear 0 at the proper times,I employ a starter-bar which may beupon the frame A and have engagement at the proper times with one or theother of two teeth on the side of one of the gear wheels P and Q, or thestarter-bar may be placed upon the driver gear 0 and the teeth may beplaced on the sides of the wheels P and Q. In such case, I prefer to usetwo starter or push bars, for convenience, though one can be used, incase the cylinder M does not make a complete revolution. It is alsoconvenient to place the teeth one on each of the gear wheels, P and Q,and to have them movable radially thereof, or the starter bar mayco-operate with teeth on the reversing or the delivery cylinder. Thefirst arrangement, Ishow in Figs. 1, 1, 2 and 3, where the starterbar ispivoted at 10 to the framework of the machine, and is fitted at itsworking end with a toothed portion 11, which rolls into engagement witheither of the two teeth 12 on the gear wheel P. Of course, the arm 11can have one, two or more teeth, and the number of teeth 12 on the wheelcan be varied accordingly. To cause the starter-bar to perform itsfunctions, I move it in this instance by means of 'a connecting rod 13,and suitable cams 14 and 15 on a short shaft 17, rollers 18 and 19 onthe rod having engagement with the cams. A suitable slot 20 in theconnecting rod 13 allows the rod to move on a loose block 13% relativelyto shaft 17 the block acting as a support for that end of the rod. Theshaft 17 has a gear 21 which is one-half the size of, and is driven by,a gear 22 on the shaft H.

I sometimes operate the connecting rod 13 and starting-bar U by cams onthe shaft H. These cams must be double; that is, the bar U must make twocomplete oscillations to one turn of the shaft H, see Fig. 1 and causethe segments R and S to successively engage the driver.

In the modification shown at Fig. 4, I employ two starter-bars U, U onthe driver gear, for convenience. These bars engage at proper times withthe yielding bars 12' and 12 respectively. The bar 12' can slide inguide lugs 28, 29, and is normally held outward by a spring surroundingit and en- 1 gaging the lug 28 and a shoulder on the bar The bar 12 ispivoted at 31 to the gear P and is normally held out by the spring 32surrounding the rod 33 and engaging against the guide lug 34 for the rod33. The bars 12 and 12 have each a tooth 11 and 11 for mesh ing with thestarter-bars U, U respectively. The starter-bars U, U have cams orinclined surfaces 35 for co-operation with the teeth 11 and 11 since attimes the teeth and bars move in opposite directions while in contact. Ialso employ, to insure the proper timing of the parts, the push lugs 23,26 on the driver gear, the lug 27 on gear Q and the'lug 24 on the gearP. Lugs 26, 27 co-operate in this wise:- When the tooth 11 runs upincline 35 on bar U there is a tendency to stop the gears P and Q, owingto friction, but the lug 26 overtakes lug 27 as the segment R rolls outof gear with driver 0 and pushes the gears Q and P on until tooth 11enters the notch in bar U at which time the driver has reached the endof its oscillation in that direction. Lugs 23, 24 co-operate in likemanner as segment S rolls out of gear with driver 0. The third form willhereinafter be described. In each modification thus far described, whenusing this device to drive the reversing and delivery cylinders, I gearthe wheels P and Q with said cylinders respectively. Gear 39 connectsgear P with the gear 40 on the reversing cylinder W, and gear 41connects gear Q with gear 42 on the delivery cylinder X. The gears 40and 42 are one half the size of their respective cylinders. It followsfrom this fact and from the fact that driver gear 0 is one half the sizeof the impression cylinder M, that the speeds of the reversing anddelivery cylinders are analogous to that of the impression cylinder. Thereversing and delivery cylinders make two turns to each stroke of thetypebed, orin difierent terms, these cylinders make four tnrns to oneturn of the crank G.

IIO

I do not limit myself to any set/number of 7 turns of these cylinders,since theycan be so proportioned a's'to make any desired number of turnsto one turn of the crank G.

The impression, reversing, and delivery cylinders are each provided withgrippers, as shown in Figs. 5, 6, 7, and 8. These grippers are worked inany ordinary way (as by cams) to cause them to operate as and for thepurposes hereinafter set forth. The sets of grippers on the cylinder Mmay be made to open, 1

by a cam, simply, when feed tapes are used to bring the sheets fromcutting cylinders, or in cases where a feed board, as 43, and gages, as44, are used, the grippers can be made to open back into the impressioncylinder M in a manner common to drum cylinder or two revolutionpresses, or as described in my patent, No. 322,132, dated July 14, 1885.Sheet cutting devices maybe used, such as are shown in my Letters Patentnumbered 456,741 and 487,495, dated the 28th day of July, 1891, and the6th day of December, 1892, respectively, or in my patent, No. 444,137,dated Jannary 6, 1891.

Cams to operate the grippers on the impression, reversing and deliverycylinders at the proper times may be connected with a side shaftcarrying cams for that purpose by suitable rods as in my Patent No.456,741 above named, such as that shown at 45. One of such cams is shownat 46, supported on the pivoted arm 47 connected to rod 45.

In carrying out one of the objects of my invention, I use the reversingcylinder W as a delivery cylinder to deliver the sheets to the fliers48. In this case, I use the removable cam 50 to open the grippers, topermit the sheet to go upon the fliers. Of course, when the cylinder Wis used as a reversing cylinder, thefiiers aremot used, andthe cam 50 isremoved. 1.2-

The delivery cylinder may deliver the sheet to fliers, as 49, or totapes to carry the sheet to a folder, and its gripper be timed andoperated accordingly.

When the inking rollers are placed adjacent the impression cylinder, asat N, each form is inked four times to each impression taken therefromwhen single or half sheets are printed, or full sheets are printed onone side only.

If desired, the sets of inking rollers may be placed at such a distancefrom the impression cylinder that one set will ink one form only, andthe other set the other form only. Such positions are indicated by thereferences N and allow space for hand-feed of sheets to the impressioncylinder M. In this case each form is inked twice by its set of inkrollers for each impression. Hence, the different sides of the sheetscould be printed in differ ent colors.

When using the machine to attain the first object of my invention, Iplace the forms for one side of the sheet at 52and'the forms for theother: side at 53,and these forms mayoccupy the entire space of the bedless the stop 51. Then for each revolution of the crankG there will beprinted an inside and an outside, and then an outside and an inside, andin this instance, the impression cylinder is not lifted from thetype-form at all.

When using the machine to print different sized sheets on both sides, oron one sheet for each stroke of the machine, I place the forms as shown,the impression being taken from one form at the stroke in one direction,and from the other form on the return stroke. To prevent imprint on thecylinder from the second form, I raise the cylinder slightly, returningit at the proper time to take the impression. I do this by the rods 54,54, springs 56 and toggle 55, the shaft of the cylinder M beingsupported in boxes 67 on rods 54, in the same manner, or one similarthereto, as in my Patent No. 425,710, dated April 15, 1890. Hence thisparticular device needs no extended description here. In this instance,I operate the toggle by the connecting rod 57 and cam 58, the rod beingslotted at 59 and sliding on and supported by a block loose on the shaft17. Rollers 60, 61, on the rod 57 engage the cam 58 as shown. This rod57 I make disconnectible from the arm 98 of the shaft 99 for a purposehereinafter described.

In cases Where to prevent set-off I use the oiling rollers 62, and whereone copy or sheet is perfected at a time, these rollers 62can be raisedby any suitable means so as not to put any oil on the portion of theimpression cylinder which takes the first impression. I prefor to use acam, as 63,.for doing this.

The operation of the various mechanisms hereinbefore described is asfo1lows:-The gear 38 is driven by the pulley 37 and belt 36, and drivesthe gear K, shaft H, gear 22 and crank pin G. The last operates the rodF, and this rod causes the gear 0 to roll on the rackEand to drive therack D and the bed B. The racks J on the bed B, which gear at all timeswith the gears L, drive the impressioncylinder M, giving it anoscillatory-rotarymotion. In the positions shown in Figs. 1 and 2, thegrippers on the impression cylinder are just a little way above thepoint where they'take the leading edge of a sheet, printed on one side,from the guides 64 leading from the reversing cylinder. Fig. 7 shows thegrippers just as they are taking the sheet, or after they have moveddown a short distance from their described positions in Figs.

IOO

1 and 2. Assuming that the type bed B is in ing edge of the as yetunprinted sheet. It

also shows a sheet long enough to print both an inside and outside, asthe cylinder moves one way. Fig. 6 shows the relative positions of theparts when the reversing cylinders grippers are grasping, and theimpression cylinders grippers are loosing, the leading edge of thesheet. (It must be borne in mind that in this instance, the rod 57 isdisconnected from the arm 98, and that the cylinder M is held down bythe toggle.) Fig. 7 shows the relative position of these parts after thecrank G has passed the dead center to the left (the position shown inFig. 1) and has moved the bed to the right a short distance, far enoughfor the grippers on the impression cylinder to be in position forgrasping the leading edge of the sheet after it has been turned upsidedown by the reversing cylinder. Fig. 8 shows the relative positions ofthese parts at the moment when the grippers of the delivery cylinder aregrasping, and the grippers of the impression cylinder are loosing, thesheet. In Figs. 6 and 8, the sheet is but little more than half printedon the bottom side. The arrows in Figs. 5, 6,7 and 8 indicate thedirections in which the parts are moving. Fig. 5 shows the parts as anew sheet is coming into the impression cylinder, and a printed one wellon its way out from the delivery cylinder. When printing on sheetsshorter than the one shown in Figs. 5, 6,7 and 8, (that is, when usingthe machine to carry out the third object of my invention,) the rod 57is connected up as shown in Fig. 2, and the impression cylinder israised and lowered as hereinafter described.

Returning now to the mechanism in the positions shown in Figs. 1, 2 and3,and remembering what has been said above about the location of thegrippers on the cylinder M, and that short sheets (see third object ofmy invention) are to be printed on, the operations of the parts are asfollows:The crank G moves downward, causing the rod F to roll the gearwheel 0 to the right upon the rack E and to drive the rack D and thetype bed in the same direction, but twice as fast as the wheel 0. Thebed B by its racks J and the gears L causes the impression cylinder M toturn. At the proper time, the gear 22, acting through the gear 21, shaft17 and cams 14,15, on the rod 13 and starter-bar U moves them to theright. Bar U, by its arm 11 and the tooth 12, starts the gear P tomoving in a direction contrary to the hands of a watch. Gear P startsgear Q in the opposite direction, and thus the segment R is thrown intogear with the driver gear 0, which now becomes the sole source of motionfor gears P, Q, the reversing and delivery cylinders and theintermediate gears, the bar U and tooth 12 having rolled out of mesh.The cam 58 and rod 57 rock the gears and 66, thus operating the toggle55 and lowering the cylinder M to take an impression from the form 53,and when the crank G is at its lowest point, these parts are almostready to raise the cylinder M so as to clear theform 52' to avoidreceiving an impression upon its surface from the form during the nextquarter turn of the crank G. The crank G, wheel 0, bed B, cylinder M,gears P, Q, 850., continue to move until the crank G is on the deadcenter to the right of the shaft H in Figs. 1 and 2. The sheet printedupon'has been taken by the delivery cylinder X and run partly on thefliers 49 or toward the folder. Owing to the relative sizes of the gears21 and 22, the starter-bar-during the half turn of the crank-will havebeen moved to its extreme positions to the right and left and will haverolled into mesh with the tooth 12 shown at the top of the gear P inFigs. 1 and 2, but which will now be at the bottom position. The segmentR is disengaged from the driver 0 when the crank G is on this deadcenter, the tooth a thereof being to the right of a line joining thecenters of the gears O and Q. The segment S is now in position to haveits tooth a engaged with the driver 0 when the gears P and Q are againput in motion by the starterbar. The crank G now' moves up and to theleft. The bed B moves from its extreme right hand position toward theleft and turns the impression cylinder accordingly. The cams 14, 15,move the starter-bar to the right, causing the segment S to mesh withthe driver 0. The driver causes the gear P to move, its top to thelefthand, and gear Q the other way. Thus it is in this instance that therecipro eating motion of-the racks J, or the oscillatory-rotary motionof the driver 0, is changed into rotary movement in the gears P and Q,or in parts geared tothem.

At the proper time, the grippers of the impression cylinder take thepaper (unprinted on either side) as shown in Fig. 5, and it is about atthis time that the cam 58, which is in the position shown in Fig. 2 whenthe crank is on either dead center, begins to rock the-segments 65 and66, causing the descent of the cylinder M to take an impression from theform 52. When the crank G is vertically above the shaft H, the cam 58has made a half turn and is rocking the segments 65 and 66 the otherway, thus raising the cylinder M to clear it from the form 53; and whenthe crank G has reached the position shown in Figs. 1 and 2, the otherparts are as shown therein.

When using this machine to print upon but one side of a sheet of anylengthup to the capacity of the machine, I use the removable cam 50 tocause the cylinder W to act as a delivery cylinder, and replace the cam58 by one shaped to rock the segments 65 and 66 so as to hold theimpression cylinder down during the stroke of the bed in one direction,and to lift it during its stroke in the other direction. I also use theflier-s48 in this case.

In Figs. 9, 10'and 11 I show a modification of the means whereby thereversing and delivery cylinders are caused to rotate each in its owndirection. In these figur'es,-the shaft H, gears" 22 and 21, cylindersM, W and X 1 are as in Figs; l, 2' and 3, the cylinder M being driven inthe way hereinbefore described.

Th'edriver gear iuthis instance is in the form of a double bevel gear,and is splinedto the shaft of the cylinderM, so as to have a slidingmovement thereon, an,d its size or pitch is one half that of thecylinder M, with which gear is shifted to its mid'position justbefore ineither direction, and is moved into contact with the gear 72 justafterthe cylinder M has begun to oscillate in theother direction. The

driver gear is moved at the proper times by the'forked lever 73, pivotedat 82, which engages the groove 81 in the gear by two pins. The lever 73is operated by the face cam 77 on the shaft 78. The shaft 78 is drivenby the shaft H through the gears 79 and 80. The

cam 77 givesgtwo throws to the lever 73 to each revolution of theshafts78 and H. A

roller on thelever 73 engages in the cam 77.

' To aid the cam: 77 in throwing the lever 73 and toprevent any unduemotion of the lever,

' I sometimes use the lever 74 on the frame A, and which is helddownwardby the spring 75,

and the toothed lug 76 onthe lever 73. A roller on the end ofithe lever74 reduces friction. In the position shown in Fig. 10 the roller is ontop of the tooth of the lug 76 ready to snap down on the outer side ofthe tooth,

since the top of the cam 77 mov es to theleft in that figure. e

To prevent shock and to secure the proper timing of the parts,Ijsometimes employ the starter-bar in this case. The starter-bar U issuitably pivoted in the framework A, and is provided with a short rackon its working end. The bar is operated by means of the 14 The lever 84:is provided withpositi've and negative rolls marked 19 and 18respectively. The working end of thestarter bar rolls into engagementwith the teeth 12 on anarm from the shaft of the reversing cylinder, andby these means gives an initiatory movementto the gears 71 and 72 at themoment the driver gear is coming into mesh with the gear 72. In thisinstance, I drive the delivery cylinder X by means of gears 68,

the gear 67 on the reversing one direction. In the position shown, the

segment 72 is the first to become engaged with the driver as thecylinder M moves its top to the left. Then as the cylinder M oscillatesin the opposite direction, the segment 72 becomes engaged, the segment72 having previously been freed from the driver. The parts marked 71, 40and W arethe same as in Figs. 9, 10 and 11 and need nofurtherdescription.

Instead of driving the type bed by the crank andwheel movement shown, itmay be driven by any other well-known means used for that purpose, or aregular mangle movement by r r means of a rack and pinion may beemployed. the cylinder M has completed its oscillation For purposes ofillustration, I have shown a machine in which the impression cylinderoscillates a little more than a full turn. I do not, however, in thispart of my invention,

limit myself to a machine inwhich the impression cylinder turns asdescribed. It ma oscillate more or less than afull'turn withoutdeparting from my invention, since the sizes or proportions of the partsmay be varied to suit the occasion. r I prefer to use the starter bar inthe moditication shown in Figs. 12 and 13, but I do not limit myself tothe use of such a bar,

either in this or any other of the cases shown, .since the parts may beso proportioned and timed in all the cases as to operate without thisbar, and I regardsuch constructions as coming within my invention.

The oiling rollers may receive oil at proper times from the fountainshown by means usually employed for that purpose.

It will be observed that, in those forms of my invention shown anddescribed, one of the driver and follower parts of the gearingconnectingthe oscillating impression cylinder with the sheet-reversingor delivery cylinder is single and the other double. ;1, 2, 4, 12, and13, the driver is single and the lfollower is double, while in Figs. 9,10 and 11 the reverseis the case.
